[Paraview] pvserver maxed out

[Utkarsh Ayachit]

Yup, that's expected. That's because of your MPI implementation. OpenMPI
does a busy wait when waiting for mpi messages. I think there's an
environment variable or something that you can set to disable that, I am no
sure. Maybe someone on the mailing list knows, or try checking the OpenMPI
documentation.
